~ Los Angeles City was founded in 1781 as a Spanish Pueblo, and was

¯u incorporated in 1850, or 69 years later~ with a population of 1600 persons.

By 1880, The City population had increased to ii~183 persons and that of

the County to 20,000~ in 1900-50 years after its incorporation-the City of

Los Angeles had a population of 102,489 and the County a population of

170,298 persons~ in 1950-100 years after the incorporation of the City-

its population was 1,970,318 and that of the County was 4,151,683 persons.

A recent Federal Census made in the Fall of 1953 found the City with a

population e.f 2 104,663, with an estimate of County population at this date,

made by ~he Los Angeles Regional ~lanning Commission of 4,750,000. Until

1940, County population has ranged from 1.6 to 2.0 times that of the City

of Los Angeles. In 1950 however, County population was 2.1 times that of

the City and in 1953 it was nearly 2.3 times that of the City.

The City of Los Angeles has added greatly to its area as well as to

its population in the past century, and is now re~u~e~ to be the largest Ci~

in point of area-in the world.

This rate of population increase-almost doubling every decade with

the exception of that of 1930-1940-has created a dynamic economy in the

area, which could naturally be expected to affect the pattern and structure

of any large community, but the period during which large numerical increas~

DISTRIBUTION OF POPULATION INMETROPOLITAN LOS ANGELES - 1950

This Figure shows the disbribution of population in Metropolitan

Los Angeles as of 1950~ the boundary of the Study Area - discussed here-

after- and the route of the proposed Monorail line.

The "ellipse" of heavy population density, extending from

Hollywood southeasterly to Compton, is served at either end by the

proposed route. The latter swerves easterly to pass through the

Central Business District of Los Angeles, a focal point of a large

amount of travel, thence southerly for some distance, from where it

passes easterly to the industrialized area, and again southerly there-

from to Long Beach.

the entire County oi’ II~<~,)(~ m~s~ 5±’um~l~,~J t~[~i<~n re<~uiirements in the

city were adequately~erve~, by two electric transit systems, which later

merged. During the 1900-1910 decade Henry E. Huntington built the

Pacific Electric Interurban Sys~ .~ connecting the City of Los Angeles

with all of the outlying population ce~ters in ~he County and the San

Fernando Valley~ and extending eastward and southeasterward to San

Bernardino, Riverside and Orange Counties. Th~s system likewise served

to collect and distribute freight throughout this four-county area.

By 1910 the City of Los Angeles had a populat~on of 319,000 and a

County population of 504,000. Trackage and service rendered by both local

and interurban transit companies were still adequate to serve transit

needs of the community. Ten years later, however~ by 1920, when the City

reached a population of 577~000 and the County of 936,000, rising construc-

tion and operating costs, with a continuation of pre-Worid War I fares

made capital investment in expansion o±’ rail transit facilities more or

less unattractive. Buses were then in the development stage and provision

of new facilities did not keep up with increased population and developed

area. Travel d~.-~÷~nces bed increased w~th increases in developed area,

and travel time had lengthened.

By this date, howe~er~ the motor vehicle had appeared. In 1921

there was one passenge~ ¯ automobile i’or ev~i~y 6.4 inhabitants of Los Angeles

County. Local residents found that it was not necessary for them to live

within a half mile of a transit line in oi’der to secure adequate transporta-

tion service in their daily movements between where they lived and where

they worked, shopped and played. They could use their automobile - because

of local climatic conditions for 365 days a year~ and they started to do

so. Settlement advanced beyond the end ~]~ rail transit lines and it was

not until the end of the 1920-1930 decade that bus service was to any

degree serving these outlying areas. The increasing number of motor

vehicles created congestion, slowed down schedules of transit vehicles-

rail and bus-transit riders took to using their own cars, and the spiral

had commenced.

Had the advent of the motor vehicle in this country occurred fifty

years earlier, other large cities in the United States would undoubtedly

have commenced this current trend towards sub-urbanization far earlier,

and population densities therein would not be what they are today. On the

other hand, had it occurred fifty years later than it did, Metropolitan

Los Angeles would today have had a far higher ~erage population density,

a much smaller developed area and undoubtedly a smaller population.

Occurring at the time that it did, the motor vehicle encouraged low den-

sity and widespread distribution of local population.

Cause of Local Population Growth

From a long local residence and a study of factors which have been

responsible for the dynamic growth in population in Metropolitan Los

Angeles, the wrioer is of the opinion that it is not the local climate but

rather the type and kind of living which such climate allows-single family

homes, with front and back yards, flowers and fruit trees, a barbecue, a

two-car garage, and in many homes two cars-and proximity to ocean~ mountain,

desert and recreational areas-practically year around outdoor living that

has caused this growth. This widespread occupancy of single family homes

has created in this area what is probably the highest standard of living

the world has ever seen.

Travel distances resulting from a City population of 300,000 and a

County population of 500~000 did not create very serious problems of daily

Page 12: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

z

z

8

movement, even with low population densities~ but when the Los ~~ngeles

City population reached 1,O00,O00 or more, and County population double

this figure~ the built up area of the community had become extremely

large. The problems of congestion and slower rates of movement began

to be acutely felt.

So far, however~ this condition has not resulted in a cessation of

population growth, as is evidenced by an increase in population in Los

Angeles County during the past 3½ years of around 600,000 persons, but

it has resulted in far more time being spent in daily movement between

place of residence and place of work.

Retail stores have moved out to the people, as is evidenced by the

widespread distribution of substantial shopping centers in the material

shown herein. Industry, however, has not to any extent changed its

general location, and the time required for people~ particularly those

employed in industry~ to travel from where they live to where they work,

has increased substantially.

Freeways as a Solution of Transportation Needs

Much talk has occurred over the past ten or fifteen years as to

the advisability of constructing a system of freeways throughout Metropol-

itan Los Angeles to provide a means of movement within the a.rea~ but pro-

gress in this construction has been very slow. The Arroyo Seco Freeway

connectin~ Pasadena with Downtown Los ~Ingeles was completed in the latter

part of the 1930-19~0 decade, and it is expected that the Hollywood Freeway

connecting the San Fernando Valley to Downtown Los Angeles will be open to

through traffic early in 19~4. The ~ona and Santa Ana Freeway should be

completed within the next two or three years. However, these Freeways will

not in any way serve the entire transportation needs of the community, as

Page 13: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

they already are now approaching congestion in the sections where they

have already been opened to travel.

The method of financing the construction of freeways in this area

by the State Highway Commission s on a "Pay as You Co" basis, which

depends upon the annual allocation from gasoline taxes, by the State, for

their construction. This method of financing cannot, because of inadequacy

of funds, provide any adequate or extensive system of freeways in this area

short of the next 25 or more years. Unless some other method of financing

is developed, it is not believed that freeway construction will begin to

keep pace with increasing population and resultant motor vehicle regis-

tration.

Factors Necessary to Maintain Future Growth ofPopulation and Present Living Standards

~ here.¯

The first requirement will be served, at least within a portion of

the area, should the proposed monorail facility be constructed. As to the

To maintain anything approaching past rates of population growth

in the area-until a point of saturation occurs-two things are necessary,

(a) the single family residential characteristic of local living must

maintained, by the shortening of the time of daily travel between place

of residence and place of work to a reasonable figure, and (b), local

residents must have the opportunity to earn their living when residing

opportunity to earn a living~ this in the last analysis depends upon the

availibility of jobs in industry. The existence of such Jobs, also in the

last analysis, depends upon the existence of markets for local products-

agricultural, mineral and industrial.

Page 14: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

Los Angeles County is today, and has been for many years, the lead-

ing agricultural County in the United States in value of its agricultural

products, largely because of the high priced citrus~ nuts and field crops

raised here. In time, with land use changes from agricultural to resident-

ial and industrial purposes, this present ranking will probably be lost,

but for many years it can be expected to continue at a high level since

land which produces agricultural crops of highest unit value per acre will

be the last to change to use for other purposes °

Petroleum is the principle local mineral product, although there is

an increasing production of non-metallic minerals in the desert back country.

0n-shore petrOleum production in the area has probably passed its peak.

Recent investigations indicate, however, the possibility of larger off-

shore reserves available for production equal in volume to the original

reserves in the Los Angeles Basin. The Tidelands Oil controversy has so

far limited off-shore activities to study and investigation, but if and

when this controversy is settled, it is expected that an active drilling

campaign would be initiated to develop this off-shore oil.

Industrial employment depends essentially upon markets for the pro-

ducts of local industry, and to support a substantial amount of such indus-

e try, distant as well as local markets must exist. Metropolitan Los Angeles,¯

~located at a considerable distance from the center of population in the

United States, is itself a rapidly growing market as are the Pacific Coast

and Southwestern States. Areas rapidly growing in population absorb con-

siderably more industrial products per capita than are absorbed in more

stable areas.

Page 15: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

12

can be expected that, as soon as conditions settle down in the Orient,

even if this requires several decades to occur, large demands will be

made upon this local area for its industrial products.

Available Data

Probably in no other large community in this country has more data

been assembled or collected, for a wide variety of purposes, than in Met-

¯ ropolitan Los Angeles. Were it not for the availability of such data, thisO

¯ Report could not have been made within the time available ¯

While all data utilized was of recent date, not all of it was as of

single date. Also, coming from numerous sources, it was found that in

some instances data on the same subject varied slightly. In no instance,

however, was this slight difference of sufficient magnitude to effect con-

clusions reached.

The rapidly growing population of the area resulted in the greatest

differences in basic data. The county population increased some 600,000,

or 1~.5 per cent between the 1950 Federal Census, taken in April of that

year, and the most recent estimate was made by the County Regional Plann-

ing Commission, ~s of the Fall of 1953. Consequently, certain derived data

~~ based upon 1950 Census figures may be somewhat low. Wherever it was possib~

¯ however, to make reasonable estimates of quantities as of 1953, this was

done.

T~ STUDY AREA

Under the Enabling Statute creating the Los Angeles Metropolitan

Transit Authority~ the latter was authorized to construct a monorail line

extending from the San Fernando Valley to the Pacific 0cea~, the loca-

tion of this line being limited, on the Coastal Plain, to within a radius

of 4 miles on either side of the Los .;ngeles River The Authority was

likewise authorized, under certain conditions, to operate buses within the

above area. Hence~ it became necessary to determine an area whose popula-

tion, workers and shoppers would be served by the proposed facility and

such feeder buses or private automobiles as would be used by potential

riders.

Area Selected

An area was selected which embraced the San Fernando Valley, in-

cluding the Cities of Burbank~ Glendale and San Fernando, and which extended

somewhat outside of the 4 mile radius specified in the Enabling Act, when

it reached the Coastal Plain. This area included population, present and

future, which it was felt would be reasonably served by the proposed facility

and feeder bus lines. It totalled 330,011 acres-515.6 square miles-or 46.9

per cent of the area designated as Metropolitan Los Angeles.

In outlining the Study Area, as it is termed herein, boundaries of

Post~l Zones or Post Office Delivery Areas (described hereafter) were used

as exterior boundaries. In establishing these latter, there was taken into

consideration present daily movement of population~ by transit facilities,

and by private automobiles on competing highways, whereby people travelled

from their place of residence to work and shop. The boundary of the Study

Area was limited to an area outside of which people would probably use

* Estimate of Los Angeles County Regional PlanningCommission for April 1953

This Study Area has contained, at least since 1930~ more than one-

half of the population in Los Angeles County, although the relative pro-

portion of such population to that of the County has decreased slightly

since 1930. It is believed that the provision of better transportation

within the Area will increase this ratio somewhat in forthcoming years.

Postal Zones

In the 1940 and 1950 Federal Censuses Los Angeles County was divided

into a series of "Census Tracts", these tracts being areas which had a popu-

lation which ranged~ in 1940, from 3000 up to 6000 or 7000. There were 580

of these tracts in the 1940 Census. Increase in population in various

sections of the County has caused the sub-division of many of these tracts,

and in the 1950 Census they numbered somewhat in excess of 700.

Various reports issued by the Bureau of Census for its 1940 and 1950

Censuses contain statistical information-in addition to population-pertainin~

Page 19: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

to each of these Census Tracts. This information has proved to be very

valuable in the present Study.

Shortly after 1940, the Research Committee of the Los Angeles Chamber

of Commerce embarked upon a project to determine and segregate the population

in the 1930 Census to Census Tracts as they existed in 1940. This was

accomplished, and at the present time there alre available "Tracted" population

figures for the County for the three Census years, 1930, 1940 and 1950.

There has been some slight shifting of Census Tract boundaries in the 19~0

Census from thcseof the 1940 Census, but for all practical purposes such

tract boundaries may be considered comparable for all three Censuses.

In the Origin and Destination Study (discussed hereafter) it was

found necessary to allocate places of work and places of residences in

accordance with information available to both employers and employees. Few

people in the County know the number of the Census Tract in which they live,

but practically every employer and employed person is familiar with his

Postal Zone or Post Office Delivery District. As a result, it was determined

to use these latter two Units (hereinafter referred to "Postal Zones") as

basis for studies of population and of travel patterns described in this

Report.

The City of Los Angeles is divided into Postal Zones south of the

Santa Monica Mountains, and the Cities of Glendale a.nd Long Beach are like-

wise zoned. The San Fernando Valley and the remainder of the Study Area is

not so sub-divided, but is divided into areas which are tributary to local

Post Offices and which are known as Post Office Distribution Districts.

In certain of the smaller Cities on the Coastal Plain, the City itself was

considered as a Postal Zone.

This study resulted in the development of 80 Postal Zones distributed

throughout the Study Area. Data pertaining to past and present population,

to location of industrial establishments~ and other employing agencies~

and to place of residence of employees~ has been distributed amongst these

80 Postal Zones. These Zones are also shown on Plate III.

POPULATION

Los Angeles County

The Federal Census of 1880 found a population of 33~381 in Los

Angeles County. Seventy years later, the 1950 Census found a County

population of ~151~687~ or 12~.~ times the population 70 years previous.

The Regional Plarn~ing Commission estimates the County popul~.tion-as of the

Fall of 19~3-to be 4~7~0~000~ or 1~2.~ times the 1880 population.

To forecast future population in an area which has for so long been

functioning under a dynamic economy is a far more difficult task than to

forecast future population in more stabilized co~unities in the United

States. Table No. 2 and Figure No. 2 sho~ Census population of Los Angeles

County from 1880 to 19~0~ and in Figure No. 2 the County population has been

projected to the year 1980.

Past and Present Pooulation of Postal Zones

The boundaries of the various Postal Zones within the Study Area

~ere not coterminous ~ith boundaries of Census Tracts~ and in practically

every case~ except ~here the smaller incorporated Cities ~ere involved,

Postal Zone boundaries cut across Census Tract boundaries. In these Census

Tracts estimates ~ere made of the proportionate area of each Census Tract

within such Postal Zone~ and the area. and population of the Census Tract

within such Zone for the 1930~19~0 and 19~0 Censuses were estimated. From

these the total area of the Postal Zone and its total population for the

above three dates ~as estimated.

The entire Study Area ~as then divided into 13 Groups of Postal

Zones~ all of ~hich~ from local kno~ledge~ had’more or less similar charact-

eristics as to population densities and rates of population increase.

PAST AND ESTIMATED FUTURE POPULATIONLOS ANGELES COUNTY-~I880 TO 1980

The writer has found, in numerous studies of population in Southern

California, that the percentage rate of population increase each decade

alternates, a decade with a percentage rate greater than the general

trend being followed by one with a rate less than such trend.

It will be noted that the rate of increase, indicated by the slope

of the line connecting points showing Census population, has this character-

istic. Rate of increase for the decade 1880-1890 is greater than the rate

of trend increase, that for the decade 1890-1900 is less, etc., etc. The

smallest percentage rate of population increase occurred during the 1930-

1940 decade, the Depression years.

As with population increases in all large Metropolitan areas, the

trend curve from 1880 to 1950 has a decreasing rate of increase with every

decade. Projected to the year 1980, the following are estimates of future

County population -

Census of 1960 5,500,0001970 6,600,0001980 7,5oo,ooo

These are believed to be reasonable figures, provided that the present sing~

family residential living characteristic can be maintained, by provision of

adequate mass rapid transit facilities and that no serious economic disturb-

ance nr international conflict occurs within this future period.

If the above trend curve were continued for another two decades, to

the year 2000, a County population of the order of 8,300,000 might be ex-

pected in 1990 and of the order of 9,000,000 by the year 2000. This, howeve~

in the opinion of the writer is too far in the future to estimate, with any

degree of assurance, the population of a dynamic community such as is Metro-

politanLo~ Angeles. See Table No. 2

Table No. 3 presents the area in acres, population for the Census years,

1930, 1940 and 1950, and the estimated population derived from figures of

the Los Angeles Regional Planning Commission for the Spring of 1~’33, as well

as the density of population for each of the 80 Postal Zones and the average

density for the 13 Groups of Postal Zones.

Future Population of Postal Zones

It is believed that the ratio of population of the Study Area to that

of the County will increase somewhat in the future, and the following esti-

mates of future population were made -

Population for each of the Zone Groups was then estimated, taking into

consideration past rates of population increases for each Zone Group,

present and ultimate probable densities and general personal knowledge of

the areas. Population of each Zone was then adjusted to total Zone Group

population. Similar procedure was followed in estimating population of

each Zone in each Zone Group Results for each Zone and Zone Group are¯

shown in Table No. 4.

Decentralization of Population

One of the most interesting facts encountered in this study resulted from

anana~ysls of population increase within a 20-mile radius of Downtown Los

Angeles between 1940 and 1950. Total population within this 20-mile radius

in 1950 was 4,051,903 persons or 97.8 per cent of the County population as

of that date. The area within this radius was divided into four quadrants

PAST AND ESTIMATED FUTURE POPULATION OF THE STUDY AREA1930 to 1980 - BY GROUPS OF POSTAL ZONES

The locations of the groups of Postal Zones designated alphabet-

Ically on this Figure are shown on Plate III. The slope of each curve show-

ing population is proportionate to the percentage rate of population

increase during each decade. Up until 1953, Groups A, I, J and M had the

greatest rate of Population increase. Following 1953, rates, except for

those of Groups A and M tend to more or less stabilize Group F includes"

the Central Business District of Los Angeles, which has shown a declining

population since 1940.

Percentage rate of increase for the 1940-1950 decade was as follows:

PERCENTAGE RATE OF INCREASEBY POSTAL ZONES

WITHIN STUDY AREA 1940-I~0

As would be expected, percentage rates of increase during this

decade were the largest in those Postal Zones at either extremity of the

Study Area - in the entire San Fernando Valley and in the Zones easterly

and southerly of the industrial area from Vernon through Compton, with the

exception of the City of Long Beach and Signal Hill.

The "core" area around the Central Business Distric% and some of

Hollywood, showed for the most part moderate rates of increase ranging

up to lO-19 per cent~ but likewise showed some areas where a slight de-

crease in population occurred. This decrease was due to commercialization

and industrialization-for the most part with light industry-of former

residential areas~ and also because of the taking for freeway purposes~ in

recent years~ of substantial areas which had a high population density in

194o.

and each quadrant was divided into Zones or Sectors of various radii,

2,5,8,13 and 20 miles, from the center of Downtown Los Angeles. These

quadrants and zones are shown on Figure No. 5, with the area and populat-

ion of each Zone within each quadrant, total area, and also population den-

sity in persons per acre for the Census years 1930, 19~0 and 1950 are like-

wise given in Table No. 5.

Densities outside of the 8-mile radius are still very low, and

encourage this trend towards single family residential living. That it is

continuing is borne out by data collected by the Los ~ngeles Regional Plann-

ing Commission. At the present time 66 per cent of the residential family

units in Los Angeles County are single fa~ly in character, and of family

units constructed between 19~0 and the present time, 77 per cent were single

fa~tly in character.

~o,puX~tlon Density

Metropolitan Los Angeles has always been characterized by a low

density of population. In the Spring of 1953, with a total County populat-

ion of ~,6~0,000 - 98 per cent of which lived within a 20-mile radius of

Downtown Los Angeles, the average population density of the area was 6.5

persons per acre. The density of the Study Area was slightly in excess of

this figure,being 7.~ persons per acre.

Of the 80 Postal Zones included in the Study Area, 13 had a population

density in excess of 20 persons per acre. The total population of these

13 Zones in the Spring of 1953 was 407,798 persons, or 16.5 per cent of the

total population of the Area. The highest population density within the

Study Area -43.6 persons per acre- occurred in Postal Zone 17, in the City

of Los Angeles, as of the Spring of 1953. There was one Postal Zone having

a population density in excess of 30 persons per acre at that time, and the

the changing distribution of population within a 20-mile radius of Downtown

Los Angeles as of 1930-1940 and 1950.

Total population as of 1950 was fairly well distributed amongst the

four quadrants, ranging from 818,553, or 20.4 per cent of the total populat-

ion, within the 20-mile radius in the Northeast Quadrant, to 1,114,478 or

27.5 per cent of this total, in the Southwest Quadrant. Population increase

during this period was the least in the Northeast ©.uadrant, being 232,280

or 17.5 per cent of the total increase, and the greatest in the Southeast

Quadrant, being 348,746, or 26.3 per cent.

Population densities in 1950 ranged from 4.5 persons per acre in the

Northwest Quadrant to 8.4 persons per acre in the Southwest Quadrant. The

average density for the entire area within the 20-mile radius was 5.6 persons

per acre(areas for which population density was computed included all hill

and mountain~ as well as valley land within each Quadrant and Sector.)

The most ~ignificant facts developed in this study were -

a. In 1930, 63.2 per cent of the total population within the 20-mileradius lived within an 8-mile radius. By 1940, this percentagehad dropped to 58..5, and by 1950 it had dropped to 45.1.

b. Of the total population increase between 1940 and 1950 of 1,327,438within this 20-mile radius, 1,090,666 or 82.2 per cent(practically

5 out of 6) occurred outside of the 8-mile radius.

c. Should this trend in decentralization of population increaseduring the 1950-1960 decade-and there is every reason to believethat it will-provided adequate transportation is provided,population increase during the coming decade outside of the8-mile radius can be expected to be somewhat in excess of1,000,000 persons, and total population outside of this radiusby 1960 can be expected to be of the order of 3-¼ millionpeople, or about 60 per cent of total population within the20-mile radius.

remaining ll of the above 13 Postal Zones had a population density of

between 20 and 30 persons per acre.

A slight loss in population between the time of the 1950 Census and

the ~pring of 19~3~ occurred in 19 Postal Zones~ these having a total popula-

tion in 1950 of 721~726. This loss in population ~mounted to 17,527 persons,

or 7.7 per cent of the 1950 population of the Study Area. This loss occurred

~ in the Zones of highest density and was due essentially to (a) the industrial-

~ izatlon or commercialization of land use in these Zones of high population

d~n~lty~ or (b) the condemnation of a substantial area of land in these Zones

for use in construction of freeways.

Lo~tion of Areas of Low Population Density

It can be expected that the large population increases numerically

as well as percentage-wise would occur in areas having at the present time

l~ population densities. Figure Nos. 6 and V present by Postal Zones

the population density in persons per acre as of 19%, and estimated popu-

latlon density in persons per acre as of 1980~ and Figure ~ shows the per-

centage increase in population from 1940 to 19~0 in Census Tracts. It will

be noted in this last Figure that the high rates of population increase

during the above decade occurred in the San Fernando Valley and also south-

erly of Los ~mgeles~ with the exception of the City of Long Beach.

FIGURE NO. 6

DENSITY OF POi~ULATION WITHIN STUDY AREABY POSTAL ZONES - 1993

This map shows that~ in spite of the fact that the greatest per-

cen~ge rate of population increase during the 1940-1950 decade occurred at

either extremity of the Study Area, population densities at such extremi-

ties are still relatively low~ and for this reason the large future in-

creases in population-provided that adequate transportation facilities

are provided-can be expected to occur in the areas of present and future

low population density.

Residential building lots-usually 50’ x 150’ in dimensions-result

in about 5 lots per acre With 3.3 persons per family, this results in

a saturation density of 16 persons per acre for strictly residential areas

of this character Since World War II~ however, fsmi!y size ~s increasing,

ar.d in new sukdivisicns cccupied Ly the younger Fopul~ation, sa.turat~on

densil;ies of from 17 to 19 per acre may be reached.

Allowing for local commercial buildings~ a few multiple dwellings~

schools and park~, saturation densities today of from 15 to 17 per acre may

occur when large areas are considered.

This map shows that there are still large areas with densities of

much less than these latter figures.

ESTI~TED FUTURE DENSITY OF POPULATIONWITHIN THE STUDY AREA - AS OF 1950

This map is based upon da~a in Table No. 5. Average population

density in 1950 is estimated as 12.5 persons per acre.

There are still a considerable number of Postal Zones where populat-

ion density in 1950 is estimated to be considerably below the saturation

point for single family residences. Zones in Groups D and F average in

excess of 20 persons per acre and in Groups E and H in excess of 15 persons

per acre.

Increased use of land for industrisl purposes in the area southerly

from Vernon to San Pedro Harbor may result in densities as ~iven in Table

No. 4~ approachin~ saturation by 1950., but there still will be considerable

room for population living in single family residences in those Zone Groups

having population densities of less than 12-13 persons per acre~ as of that

date.

ECONOMIC CHARACTERISTICS

While this Report does not deal essentially with economic character-

istics of the general area~ it was thought advisable to present a small

amount, of material pertaining to this subject.

Median Value of Owner Occupied Single Family Homes - 1950

Figure No. $ shows by seven brackets the median value of single

family owner occupied homes within the Study Area. As with income, most

seotions in which the higher value homes occur are located outside of the

Study Area.

Median Income Per Family - i950

Figure No. 9 shows the range in family income in six different

brackets. Most of the high family income areas are without the Study Area.

Econom/c Indices

Figure No. i0 and Table No. 6 present certain Indices for the Los

Angeles Metropolitan Area over the past three or more decades. Gasoline

Sales are for the entire State of California, as such sales in individual

Counties of the State are not reported 3epara,tely.

FIGURE NO. $

Y~IAN VALUE OF OWNER OCCUPIED SINGLE FAMILY HON~SWITHIN STUDY AREA - 1950

This factor is usually considered to be a very good indicator of the

economic status of residents within any area and may be considered to be so

in those Census Tracts having relatively low population densities, but a

comparison with Figure No. 9, Median Income per Family, will not show very

good correlation between Median Velue of Homes and Median Family Income, for

all Census Tracts,for the following reasons.

In many areas of hi~her population densities, a considerable number

of inhabitants therein live in multiple dwellings, and for the most part,

single family homes, while having a high value, house a pelatively small pro-

portion of the total population, with residents of multiple dwellings being

in asomewhat lower economic bracket. Consequently, high values of single

family owner occupied homes do not refLoct high income in these Tracts.

High population densities also occur in the older sections of the

area, where single family homes were built many years ago before present

costs levels existed. Furthermore, the market for such older homes is not

great, further resulting in lower values. In m~st of the areas where median

~alues are in excess of $ ~000, homes have been built in recent years during

the era. of high construction costs.

In the Census Tracts not colored, no data was given in the Census

Reports as to this factor.

FIGURE NO. 9

MEDIAN FAMILY INCOME WITHIN THE STUDY AREA - 1950

This map indicates Median Family Income as of 1990, in each Census

Tract within the Study Area. In general, such income ranged from $ 2900

to $ 4900 per year, except in a small area in Holls~rood, within Downtown

Los Angeles and within an area southerly and southwesterly therefrom, in

the Watts area westerly of Lynwood, and in a small area along the Ocean in

Long Beach, in which areas Median Income ranged from under $ 1900 up to

$ 2500 per year.

Areas with Median Income in excess of ~ 4900 per year are few in

number within the Study Area, as most of such areas in the County occur in

Pasadena, Beverly Hills, Westwood, West Los Angeles, the "Malibu" and Palos

Verdes, all of which are outside of the Study Area.

Experience in other communities where mass rapid transit facilities

exist shows that areas having family incomes within the $ 2900 to $ 4500 per

year bracket develop a higher riding habit on such systems than those where

incomes are in higher or lower brackets.

In Census Tracts not colored, no data regarding income was given in

the Census Reports.

FIGURE N0. i0

ECONOMIC INDICES-METROPOLITAN LOS ANGELES-1920-1953

Various Economic Indices pertaining to Metropolitan Los Angeles are

shown on this Figure. They all show an increase from 1920 through 1929~

except that the Index for Building Permits declined during the early 1930’s

and, with the exception of Building Permits and Number of Production Workers

¯ in Manufacturing and the Motion Picture Industry~ all showed a continued ri~

~ following the early 1930’s. The general rate of increase in all Indices,

except the foregoing, following this 1930-1935 period was considerably in

excess of the rate of increase of population.

The initial decline in Building Permits during the 1920’s probably

indicated that the local population was becoming adequately housed, and that

industrial plant construction had slowed down, while the decline in this

Index during the 1941-1943 period was due to lack of availability of building

materials and of construction labor .

The most significant fact in this graph is that, while the Index for

the number of production workers dropped sharply from in excess of 300% in

1943 to well below 200% in 1946, and then continued at around this level for

several years, other Indices~ the Areal Economic Index and the Indices of

Bank Debits, Department Store Sales, KWH Power Sales and Building Permits,

did not reflect this decline. This would indicate that production workers,

laid off from War Industry, still had money to spend and had foun~ Jobs at

which to earn such money.

The extremely high rise in Building Permits would indicate that many

of these former production workers secured employment in construction, resi-

dentlal and industrial, and the continued rise in KWH Power Sales, after a

short drop following 1944, also would indicate that Post-War industrial

aotivity recovered fairly rapidly. See Table No. 6.

PASSENGER AUTOMOBILES

Los Angeles County has the greatest density of passenger automobile

registration - expressed as the number of persons per registered automobile-

or conversely - as the number of automobiles per 1000 population, of any

large metropolitan area in the United States, which means in the World. This¯

~~ fact~ the relatively low population density~ and the prevalence of single

u¯ family residential living, are all closely related.

Densit~ of Passenger Automobile Registration in i0 LargestCounties in the United States 1951-19~2

As of 19~1-19~2~ there were 2.76 persons per passenger automobile in

Los Angeles County, or 363 passenger automobiles per 1000 County population.

The Five Boroughs of New York City had 7.03 persons per passenger automobile,

or 1~2 automobiles per 1000 population.

D~n~t~ of Passenger Automobile Registration - Los Angeles Count~Pa~t and Estimated Future

In 1953, there were an estimated 1,895~000 passenger automobiles

registered in Los Angeles County, or 2.~3 persons per automobile-412 per

~~ i000 of County population. This increase in the number of passenger auto-

¯ ~l:~blles has been much greater than the increase in population~ as is shown

on Figure No. 12 and T~le No. 8.

Statutor~ Requirements for Garages in Residential Buildings

Ever since 1930, the City of Los Angeles has specified by Ordinance

that one garage or storage space for an automobile must be provided for

every family dwelling unit constructed, whether such unit be a single family

or a multiple dwelling. Today no one thinks of building a single family

PAST, PRESENT AND ESTIMATED FUTURE PASSENGER AUTOMOBILEREGISTRATION IN LOS ANGELES COUNTY 1921 - 1980

Total number of passenger automobiles registered in Los Angeles County

have shown a continuous rise since 1921, with the exception of a few years

in the early 1930 decade, during the Depression, and also during the early

years of World War II, when the number declined slightly.

The mumber of persons per passenger automobile also continuously de-

clined , except for these two periods, and in 1953 reached a low figure

(a high density) of 2.43 persons per car, or 412 passenger automobiles per

lO00 County population.

The curve of persons per car, from the trend of the curve following

1946, might have been projected from a high of 3.16 in that year down to

around 1.5 in 1980~ but it is believed that other factors will come into

play, economics, availability of garage accomodations, traffic congestion,

which will prevent it from dropping to this low figure. Some reduction can

be expected, however, and the curve has been flattened out by 1970 at a

figure of 2.1 p~rsons per car. This indicates a total passenger automobile

registration of 3,700,000 passenger cars by 1980, about twice the present

n~mber.

residence without at least a two car garage~ as the place would neither be

salable nor rentable. Today every sixth family owns two cars, and at the

rate that this multiple ownership is increasing, it will not be long before

this will be reduced to two cars for every fifth family.

Effect of Improved Transit Facilities uDon Density ofPassenger Automobile Registration

It is not believed that improved mass rapid transit facilities will

have any great effect on this trend in multiple ownership of automobiles.

The widespread and increasing decentralization of shopping centers through-

out the MetropolitanArea will tend to maintain the trend. Many workers

will still use their cars to reach transit stations. Reduction of long

distance automobile travel, which the provision of mass rapid transit facil~

ties will tend to encourage, combined with an increase in mileage of freeways

should reduce the present congestion on arterial highways, and encourage

their wider use.

Should the family car be left at home, the housewife will find many

additional needs for its use. It is the teen-age generation, and those a

few years older, however, who are largely responsible for this multiple

ownership of cars. These young people have their friends, and the parents

have theirs~ and the two groups are different and usually live in different

localities. Automobiles pass through a number of ownerships today in their

total life of 12 to 14 years, and the old age of many of them is spent in the

hands of this younger generation.

Week-end travel to recreational areas mountains, beaches and desert-

is very extensive. Seldo~ do parents and young people go to the same place,

and this is a strong argument for the second car in the family.

The strongest argument, however, lies in She fact that passenger

Page 64: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

automobile density (expressed as number of such automobiles per lO00

population) varies inversely with population density (expressed as number

of residents per acre). As long as this area maintains its low population

density~ it will maintain its high passenger automobile density.

THE CENTRAL BUSINESS DISTRICT OF LOS ANGELES

Up until about 1920, the Central Business District of Los Angeles,

or Downtown Los Angeles, as it is commonly known, was the dominating business

conter of Metropolitan Los Angeles. Practically all office buildings, all

department stores~ specialty shops, and other retail stores, except the

usual neighborhood stores, were located there °

Such District is normally taken to extend from Sunset Boulevard on

the North to Pico Boulevard on the South, and from Figueroa Street on the

West to Los Angeles Street on the East, although various other boundaries,

closely approximating these, have also been used.

vehicles entering the Central District, summarized in three groups of Streets

Figure No. 13 presents in detail the number of motor vehicles enter°

in, Downtown Los Angeles in 1950, by streets of entry and departure.

Decentralization in Retail Trade - 1929-1948

In 1920, Los Angeles City had a population of 576,000 and the County

of 936,000. By 1930, the City population had increased to 1,238,048 and

the Ceunty population to 2,208,492. The increase in City population was

662,000 and in County population was 1,272,000. At the same time passenger

automobile registration had increased from 171,624 in 1921 to 776,677 in

1930, or by 605,053. No figures are available as to the location of tke

FIGURE NO. 13

NUMBER OF MOT(Z~ VE_HICL_E. S ENTERING THECENTRAL BUSINESS DISTRICT OF LOS ANGELES -1950

This is the last complete Cordon Count made of motor vehicles enter-

ing the Central Business District of Los Angeles, although some counts have

been made on individual streets since 1950. This count was made prior to the

opening of the Hollywood or Harbor Freeways to traffic. At the present writ-

ing they are not yet open throughout their entire length, but are used to a

substantial extent by local traffic The Hollywood Freeway, since it has

been partially opened, has taken a substantial amount of traffic from Sunset

Boulevard, Temple, First, Second and even Third Streets¯

Figueroa Street carried the largest volume of traffic, both in and out-

bound, this being essentially traffic from Pasadena and neighboring communit-

ies travelling to it over the Arroyo Seco Freeway. Olympic Boulevard carries

traffic from Santa Monica and Western Los Angeles directly into the lower

part of Downtown Los Angeles. At this date, Fifth and Sixth Streets were

one-way streets, and recently Eighth and Ninth Streets have been made one-way.

The heavy traffic along the East and West sides of the area is due n~

alone to the greater length of these sides, but likewise to the fact that a

great deal of through traffic moves in this direction, between residential

areas to the West and wholesale and industrial areas to the East of the Cent-

ral Business District¯ A study made in 1939 indicated that 35 per cent of

the traffic entering the Central Business District in an East and West dir-

ection moved directly across it without stopping¯ Eliminating this percen-

tage of through moving vehicles, from entering and leaving traffic, the numbe~

of vehicles entering and leaving across the East and West boundaries, in spit~

of the far greater length of the latter, is but about l0 per cent greater

than those entering and leaving on the North and South sides.

increase in areal population between 1920 and 1930, but it undoubtedly

occurred in peripheral areas. Distances had become great, traffic con-

gestion had increased and decentralization of trade was under way.

The trend in this decentralization is shown in Table No. 10, the

M~Jor Economic Areas being indicated on Figure No. l~.

Another significant fact in connection with the decentralization of

Downtown Los Angeles is the fact that but three office buildings have beem

constructed in Downtown Los Angeles since 1930, all in recent years~ while

many older buildings have been torn down to make way for parking facilities.

Number of Persons Entering Downtown Los AngelesDuring an Average Week Day 192~ to 1980

From the cordon counts of motor vehicle traffic made between 192~ and

19~0, from scattered data as to persons per passenger automobile, and from

other scattered traffic counts, as well as from data supplied by the Pacific

Electric Railway and the Los Angeles Transit Lines~ it has been possible to

estimate the number of persons entering DowntownLos Angeles during a 12-houx

week day at various times between 1924 and 19~3.

When these numbers of persons enterlngw~eexpressed as the numbers

per lO00 County population at each date, a trend curve developed which allow-

ed a projection of the number entering per 1000 County population up to the

year 1980.

If present conditions as to transportation and parking facilities con-

tinue it can then be assumed that Downtown Los Angeles has become stabilized

Every available ~acant parcel of land not occupied by a building is use~ for

a parking lot, and a number of parking garages have been constructed and are

heavily used. The only ma~uer by which parking capacity in the area can be

increased will be to construct more parking garages~ and/or to tear down

more existing buildings and convert the area that they occupy to parking

lots or garages.

ECONOMIC AREAS - LOS ANGELES COUNTY

This map locates the Major Economic Areas within the County for

which volume of Retail Sales are shown in T~.ble No. 10.

Data presented in this Table emphasizes the extent to which decent-

~ ralization of Retail Trade has taken place since 1929 in Los :~ngelesZ

~ County. In that year, out of every $ 1.O0 spent in Retail Sales in the¯

County almost 30¢ was spent in Downtown Los ~ngeles, while in 1948, this

30¢ had dropped to slightly more than ii¢.

The Northeast, East, Central, including Downtown Los ~ngeles,

Hollywood, and the balance of the County, all had lost their relative

positions as retail trading centers between 1929 and 19~8 ,

Downtown Los ~ngeles, as considered in these figures, extends from

Temple Street southerly to Jefferson Boulevard, while normally it is con-

sidered to extend from Sunset Boulevard southerly to Pico Boulevard .

Volume of trade between Temple and Sunset, and between Pico and Jefferson

is relatively small.

NUMBER OF PERSONS ENTERING THE CENTRAL BUSINESS DISTRICTOF LOS ANGELES DURING 12 HOURS ON ANAVERAGE WEEKDAY

1924 to 1980

This Figure is presented in connection with Table No. ll, which is

based upon available cordon counts and other traffic counts adjacent to the

Central District, upon data from the Pacific Electric Railway and the Los¯

~~Angeles Transit Lines~ and from a 1944 Report of the Los Angeles County

¯ Regional Planning Co~ssion.

The curve expressing total number of persons entering the Central

IDistrict per i000 total County population shows a very definite downward

~ trend. In 1924, the number entering was equal to ~13 per 1000 County pop-

m ulation. At the present time this number has dropped to i~2 per 1000, and

~z by 1980 it is estimated that it will be about 80 per 1000. This last

~ figure, naturally~ is based upon the assumption that transportation and

u parking facilities remain at about what they are today.

~ A further interesting fact, based upon this projection an~ upon

estimated future County population~ is that there have not been~ nor will

there be - up to 1980 less than 600,000 nor more than 700,000 persons

entering the Central District daily~ and that in 1980~ there will be fewer

¯ persons entering such District daily than have entered it since 192~, when

County population was slightly in excess of 1,~00,000 persons.

Los Angeles Area. were primarily radial in direction, like the spokes of a

wheel. Since that time, decentralization of business~ extension of the

populated area and increased industrialization in outlying sections, parti-

cularly since the early 1940’s,have resulted in a substantial increase in

circumferential traffic.

Many automobile riders who formerly drove through the Central

District from one side of the Metropolitan Area to the other now drive

around it Morning and evening peaks made up of industrial workers are.

creating conditions which are approaching, if not reaching congestion.

Plate IV presents the traffic flow-in both directions-on certain State and

other highways in the area for the year 1948, and-in a different color,- the

increase in such traffic during the five year period 1948 to 1953.

The shortage of passenger automobiles, created by cessation of pro-

duction during We~d War II, had not beeneliminated by 1948, there being

1,333,718 passenger automobiles registered in Los Angeles County in that ye~.

This number had increased to 1,895,000 or 42.2 per cent by 1953. While pop-

ulation of the County had only increased by 22.5 per cent during this 5-year

period. While in future years, the increase in number of passenger automoo

biles may be expected to follow more closely the increase in population,

decentralization of the latter may be expected to cause a substantial increas~

in this circumferential traffic, unless provision is made to handle a consid-

erable amount of such traffic on mass rapid transit facilities.

Southbound Passenger Automobiles and PassengersTravelling over Cahuenga Pass - July 1953From 6:00AM to 10:00PM

This count~ made in connection with the annual traffic count of the

California Highway Commission, was primarily to determine car riding habits,

from which the number of persons leaving the San Fernando Valley during a

16-hour day could be estimateed. Because the Freeway over Cahuenga Pass is

not as yet connected with the Hollywood Freeway-although such connection is

expected to occur early in 19~-it was not possible to determine the pro-

portion of these passengers coming from the Valley who travelled directly

to Downtown Los Angeles, and those who followed a circumferential route

around this area to points on the opposite side~ or who travelled southerly

or westerly from Hollywood.

Distribution of Rail and Vehicular Travel over 24 Hours

Transit riding habits, shown on Figure No. 17~ are typical of those

in large Metropolitan Areas in this Country~ except that morning and evening

peaks are sharper and mid-day and evening traffic is smaller, these charact~-

istics being undoubtedly due to the high passenger automobile registration

and decentraliza-~on of retail trade.

Freeway Construction Program,

Figure No. 18 shows the present state of Freeway development in

Metropolitan Los Angeles~ and probable rate of future Freeway construction

under present methods of financing. The present system of financing high-

ways, based upon State collected gasoline and user taxes, with some Federal

allocations, with these revenues being allocated to Cities, Counties and the

State system according to a formula, has been in effect for three decades.

This system operated very well while the number of registered motor

vehicles was relativel~ small~ but today, when freeway construction is

DATA PERTAINING TO SOUTHBOUND PASSENGER CAPS AND PASSENGERSTRAVELLING OVER CAHUENGA PASS DURING THE PERIOD

6: 00AM to I0: 00PM, JULY 195B

This Figure presents some of the data given in Table No. 12. A

portion of the passenger automobiles travelling southbound over Cahuenga

Pass continue directly down Highland Avenue to and through Hollywood, while

the remainder travel easterly to the eastern section of Hollywood and beyond,

via Cahuenga Boulevard. The Hollyw~rod Freeway is not yet connected to the

Freeway through the Pass

Of a total of 47,658 passenger cars travelling southbound over the

Pass, 29,289, or 61.5 per cent, travelled via Cahuenga Boulevard, and 18,369,

or 38.~ per cent, passed down Highland Avenue. Of the total of 70,797

passengers, 44,~34 or 62.8 per cent travelled via Cahuenga Boulevard, and

26,363, or 37.2 per cent, travelled down Highland Avenue.

Passengers per car started out at slightly over 1.3 in early morning

hours, and gradually increased to around 1.5 by 6:00PM, and then increased

fairly rapidly until 9:00PM, after which time they dropped off in number.

Between 7:00 and 9:00AM, 20.9 per cent of the total passengers moved, and

between 7:00 AM and 10:00AM, this proportion was 29.7 per cent, or a total

of 50.6 per cent of the total l~ hour traffic in these ~ hours. The slight

evening peak, between ~:00 and 6:00PM, is apparently made up of persons

working in the San Fernando Valley and living south of the Pass, while the

later peak between 7:00 and 9:00PM, is probably made up of pleasure seekers

coming to Hollywood~ and of persons travelling to Los Angeles from distant

points in the northern or central part of the State.

HOURLY DISTRIBUTION OF VEHICULARAND TRANSITPASSENGER TRAVEL OVER 24 HOURS

This graph, based upon data given in Table No. 13, shows hourly distribution

of passenger and vehicular travel on the lines of the Pacific Electric Rail-

way, the Los Angeles Transit Lines, and on the Hollywood and Arroyo Seco

Freeways.

The morning peak transit travel, between 7:00 and 9:00AM, accounts

for 23.9 per cent of the total 24 hour passengers on the Pacific Electric

Railway, and for 19~3 per cent on the Los Angeles Transit Lines, with the

evening peak~ between 4:00 and 6:00PM accounting for 29.7 per cent of the

.total 24 hour passengers on the Pacific Electric P~ilway, and for 22.5

per cent on the Los An6eles Transit Lines. Thus, these four peak hours

account for travel of 49. 2 per cent of the total passengers on the Pacific

Electric Railway and for 41.8 per cent of the total passengers on the Los

Angeles Transit Lines.

Travel during offpeak hours, during the middle of the day and after

6:00PM is heavier on the Los Angeles Transit Lines than on the Pacific

Electric Railway, and this accounts, at least to a considerable extent, for

the fact that travel peaks on the Pacific Electric Railway are somewhat

higher than those on the Los Angeles Transit Lines, when expressed in terms

of total 24 hour passenger travel.

essential, particularly in the Metropolitan Areas of the State, and with

the extremely high cost of such Freeways compared with costs of arterial

highways, it has not provided sufficient funds annually to allow such free-

way construction to keep pace with the increasing demands of motor vehicle

traffic for them.

An effort was made in the 1953 State Legislature to provide a large

~ bond issue~ debt service upon which would have been met from future gasoline

O~ and user taxes, in order to accelerate freeway construction in Metropolitan¯

Areas, as well as to make up deficiencies in other highways, which was not

successful. Another bill creating a Freeway Authority for Metropolitan

Los Angeles~ which would have imposed local gasoline and possibly other

taxes, using such revenues for debt service on a large bond issue, to be

likewise used for accelerating local Freeway construction.~ failed of passage.

It is the opinion of the writer, as stated in the Foreword of this

Report. that, irrespective of whether the proposed rail facilities are con

structed, some method of financing Freeway construction in Netropolitan Los

Angeles, which will allow early completion of a Freeway network adequate to

I care for present traffic and which will allow such a network to keep pace

with increasing population and motor vehicle registration, is an urgent

~ necessity.¯

Such Freeway network will be needed particularly to serve those

areas where present population densities are low and travel patterns are not

now, nor will be for some time in the future, of a character to provide suf~

cient revenues to support rail mass rapid transit, until such time as den-

sities and travel patterns in these areas will provide such support.

PRESENT AND FUTURE STATUS OF FREEWAY DEVELOPI~NT

The following indicate briefly the present and future status of Freewaydevelopment in Metropolitan Los Angeles, during the next few years.

HARBOR FREEWAY - Now open to Sixth Street. Section from Sixth to OlympicBoulevard scheduled to open in early 1954, Section to 23rd Street undercontract, scheduled to open about the middle of 1955. Construction bidsto Exposition Boulevard to be advertised early in 1954, with this sectionto be opened in the middle of 1956. Construction bids to Gage Avenue to beadvertised in latter part of 1954, with opening of this section early in1957. Southern end from Lomita Boulevard to Battery Street, San Pedro, tobe advertised for bid in early 1954, and opened for use the latter part of1956 Right-of-way acquired on all remaining sections. Construction to

"proceed as funds become available.

LCS ANCEIES RIVER F~E~~AY - Completed north of 223rd Street. Under con-struction to south crossing of Atlantic Boulevard. Right-of-way beingacquired north to Olympic Boulevard, with section from Washington Boulevardto Olympic Boulevard scheduled for initial construction.

HOLLYWOOD - RAMONA COHNECTION- Aliso-Alameda Street underpass scheduled foropening the end of 1953. Vignes Street separation to be completed about theend of 1954.

HOLLYWOOD FI:~IEWAY - Completion of section through Cahuenga Pass scheduledfor completion early in 1954. Extension westerly to Ventura Boulevardprobable. Extension north to San Fernando less probable.

GENERAL COMMENTS - Riverside Parkway route adopted, San Fernando toArroyo Seco. Extension of Riverside Parkuay from Arroyo Seco southerly toRamona and Santa Ana Parkways, with Olympic Freeway, thence westerly toSanta Monica appears likely. Santa Monica Parkway through Beverly Hillsappears unlikely. Sepulveda Parkway route adopted but time of initiationof construction indefinite.

VIII

ORIGIN AND DESTINATION STUDY

In an investigation of this character it becomes necessary to secure

information as to the location of residence and place of employment of pote~

tlal passengers who might ride a transit facility to be constructed, and

also as to their movement and pattern.

Location of Industry

Plate II shows the location of land now occupied by industry. It

will be noted that such industry is located in the area extending from the

southeastern portion of Los Angeles in a southerly direction. That this

general locational trend will in all probability continue in the future is

indicated by the location of land now zoned for industrial purposes.

Naturally, some scattering of industrial use may be expected, but the

pattern has been set for this continuation, by the location of existing

industrial uses and the zoning of land for expansion of these uses "

Other considerations will likewise influence the continuation of this

trend, proximity of rail lines and highways, and of the Forts of Long Beach

and Los Angeles, available water supply, and, with provision of adequate

transportation facilities~ an adequate labo~ supply.

Persons Included in Study

Because of the availability of information, thepresent study was

limited primarily to employees of industry~ with the exception of Postal

Zones 12, 13, 14, 15 and 17~ these being Downtown Los Angeles, and 28, Holly-

wood. In the aforementioned Zones the employees included those working in

the retail stores, hotels, etc., and also occupants of office buildings. All

persons covered in this study are employed and therefore constitute the major

portion of the potential traffic during the morning and evening peak hours.

Page 90: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

Industrial Establishments Included in Study

The Los Angeles Chamber of Commerce in 1952 published a Directory

of all industrial establishments in Los Angeles County, employing 25 or

more persons, giving the street address and Postal Zone of each industry

or plant in the County. These industries were classified-as to number of

employees into the following groups-25 to 49 employees; 50 to 99 employees;

i00 to 249 employees; 250 to 499 employees; and 500 or more employees. The

total industrial employees in each Zone were estimated by taking the avera~

number employed in each group and multiplying such number by the number of

plants listed in each Zone in each group. For example, in the group employ-

ing between 25 and 49 employees, it was assumed that average number employed

was 37. This number was multiplied by the number of plants in the Zone in

this group to secure the number of estimated industrial employees in that

Zone.

This method is considered statistically sound, as the number of firms

in each group was large. The number of employees in those firms employing

in excess of 500 persons was in most instances secured directly from the

I employer, and in the few instances where such information was not available,

the number was taken as the average number of employees per firm in the

~~ 500 or more group.¯

Procedure Used in Securing Employee Addresses

Addresses of employees segregated as to Postal Zones were secured by

a number of methods- personal solicitation, telephone calls and by mail.

In quite ~ few instances local Chambers of Commerce in smaller communities

gave excellent cooperation. In securing this information some employers

furnished separate 3" x 5" cards for each employee with their name and

residence address; and in most insta.nces~ the Postal Zone in which such

Page 91: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

employee lived. In a small percentage of cases the employees address card

did not give the Postal Zone of his residence.

When the number of addresses lacking Postal Zone identification

formed a fairly sizable proportion of the total persons employed at a plant,

a 25 to 50 per cent sample of such unzoned addresses was taken, and Postal

Zones of such addresses determined from a Street Directory which gave Postal

~ Zones. Where the unzoned addresses constituted a relatively small proportion,

O~ they were proportioned between employees who lived in the Study Area and¯

those who lived without it. As was to be expected~ a large number of employee~

Iwere found to live outside of the Study Area. This group was set aside,

however~ for use in any future studies.

Other employers and groups supplied the data on forms supplied to

them, these forms giving the total number of persons employed by them at each

plant or business location in each of the 80 Postal Zones.

Expansion Factor

While it was not possible to secure a 100 per cent sample of all

employees, the percentage was quite high in the majority of Zones, being in

excess of 50 per cent of those employed in industry in the Area, as is shown

~in Table No. 14.

¯ It then became necessary to expand this sample to include all of these

persons employed in industry in each Postal Zone. Inasmuch as the size of

the sample was substantial, it was assumed that the residence pattern for

all employees in each Zone was the same as that indicated by the sample. To

the ~l~uown number of employees working in a given Zone and living in each of

the 80 Postal Zones, an "Expansion Factor" was applied, this being developed

as follows.

Page 96: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

The total figure for employees estimated to be working in the given

Postal Zone was divided by the figure for employees whose Postal Zone

address was known, the result being considered as the "Expansion Factor".

The following hypothetical case illustrates the procedure.

Assume that there were an estimated 2500 persons employed in Zone 35,

who lived within the Study Area, and that of these, Zones of residence were

available for 1500 employees. The "Expansion Factor" for Zone 35 would

therefor be 2500 ¯ 1500, or 1.67. If information was received to the effect-

that 30 employees who worked in Zone 39 resided in Zone 22, this latter

number was expanded by multiplying by the factor 1.67 (30xi.67) and it was

estimated that of the total 2500 persons who worked in Zone 35, 50 resided

in Zone 22.

Table No l~ shows that there was a total of 597,068 persons employed.

in these 80 Zones, that data as to Zone of residence was received from

320,855 persons, making the "Expansion Factor" for the entire Study Area 1.86

This includes the Zones in "Downtown Los Angeles" mentioned above, and also

the Holls~ood Area.

Because of the preponderance of non-industrial employees in Downtown

Los Angeles and in Hollywood, an effort was made to determine Zone addresses

of employees of retail stores, hotels, financial concerns and public agencies

and occupants of office buildings.

In 1949, the Downtown Business Men’s Association made an estimate of

the total number of persons who entered and remained in the Central District

during the 16 hours, 6:00AM to IO:OOPM, using then available sources of

information, and this was used as a bases for the Origin and Destination

Study in this area, being expanded as described below.

The area included in this Study extended from Sunset Boulevard on the

north to Pico Boulevard on the south, and from Figueroa Street on the west to

Page 97: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

8O

Los Angeles Street on the east. The five Postal Zones which make up this

area cover a considerably larger area than that given above, and it was

felt that the Downtown Business Men’s Association Study should be expanded

to cover the five Postal Zones.

To the 22~343 Governmental employees included in the estimate of the

Downtown Business Men’s Association estimate, 15 per cent was added, mak-

~ ing an estimated total within this employment category of 25,694 employees.

~ City~ County and Federal Agencies reported residence addresses of 21,448¯u employees. This providing an "Expansion Factor" of 1.20 (25694 , 21448).

A total of 4821 addresses of industrial employees working in plants in

these Zones was received. Total employees estimated to be working in these

Zones, based upon the categories in the Chamber of Commerce publication,

were 10,993 which gave an "Expansion Factor" of 2.25(10993t 4821).

No information as to employees in smaller retail stores in this Zone was

received from the Downtown Business Men’s Association, although those

employed by the large department stores were included.

Zone 13 The Downtown Business Men’s Association reported addresses of

7053 persons employed in stores in this Zone and an "Expansion Factor" of

~ 1.50 was arNitraril~ assumed. It was also found by canvass that 6165

¯ occupants of office buildings in this Zone existed and an "Expansion Factor"

of 1.7 was erbltrarily assumed, giving a total of 10,481 occupants of offi~

buildings in this Zone. Replies were received from industrial employers

giving the residence addresses of 1826 persons employed in this Zone. The

estimate from the Chamber of Co~nerce Bulletin of total industrial employees

therein was 4738 persons, resulting in an "Expansion Factor" of 2.59 for this

Zone.

no data was available on this point, it was arbitrarily assumed that

75 per cent of these 23,060 persons were employed in Zone 28, or a total

of 17,300. Based upon data in adjacent Zones, it was assumed that 10.2

per cent of the 17~300 employees or 12,150, lived in the Study Area and their

residential addresses were distributsd in the pattern found by occupants of

office buildings and industrial workers.

It is realized that the quality of the results of this Study is not

~ as high as is that developed from industrial employees, but it does take in

¯

ccnsiderably ~ore employees in other categories, and in all probability tl~

final results are of reasonable quality.

Other Potential Passengers

As stated above, all potential passengers, except those in Downtown

Los Angeles and in Hollywood, are industrial employees engaged in manufact-

uring industry. In addition to these employees, however, there are a sub-

stantial number of employees in other industrial categories.

In the Community Labor Market Survey of the California State Depart-

ment of Employment~a total of 1,486,000 persons were listed as being employed

in ii employment areas as of July 1952. These employment areas cover very

~ closely the Study Area. The number of employees in each employment area in

¯ each category are listed in Table No. 15.

Manufacturing had the greatest number - 436,500 - followed by Whole-

sale and Retail Trade 342,900 - and then Service - 248,100. Employees in

Manufacturing constitute 29.7 per cent of the total number of employees, and

the above three categories include 1,026,000 persons, or 69.0 per cent of

the workers in these Ii employment areas.

Table No. 16 was prepared to show the number of employees in each

employment area and under each category, per i000 employees in Manufacturin~.

Page 99: REPORT THE LOS ANGELES METROPOLITAN …media.metro.net/images/monorailpart2data.pdfreport to the los angeles metropolitan transit authority on a monorail rapid transit line for los

For example, in the Huntington Park area there were 124,500 employees in

Manufacturing, and 34,400 in Wholesale and Retail Trade, or 277 per i000

Manufacturing. For every employee in Manufacturing there were a total,

including those in Manufacturing, of 4,056 employees in the 13 employment

Zones.

Nearly all of these employees in Manufacturing could be considersd as

Dotential users of this transit facility if it is constructed. This is not"

true, to as great an extent, with employees in other industrial categories

due to various reasons, their residence being close to their place of employ-

ment, their need to use their own automobile in their daily work and similar

reasons.

No information is available on this matter nor as to the location of

residence of employees in other than the Manufacturing category. To secure

some idea of how many of these employees in other categories would also be

certain assumptions, these being based largely upon local knowledge of

employment characteristics.

The results of these assumptions are Shown in Table No. 17. Under

each category an assumption was made as to the total percentage of employees

in each employment category who would be potential users of the proposed

transit facility. For example, it was assumed that only 5 per cent of those

potential users in the proposed facility, it becomes necessary to make

employed in the category of Fishing and Agriculture would be potential users

of the proposed facility, i0 per cent of those employed in the Mining categor

(including oil workers)~ 7½ per cent in the Construction category, etc.

the Burbank employment area., for example, there were 68 employees in the

Fishing and Agriculture category per i000 employees in Manufacturing.

Applying the 5 per cent Factor to this number it developed that but 3

employees per lO00 employees in Manufacturing would be potential users of the
